reaching free space with SAP DB on Windows

Hi!

I am using SOLMAN with SAP DB on Windows and (funnily enough) reaching the free space on my computer (no arching mode is activated).

Can some one tell me how to proceed in this case (can I put away the log files or the data files that are not being used). How can I extend the free space without much effort?

Is there some useful transactions (like db02 in oracle) to manage the SAP DB?

Thank you!

regards
